Specicati-on of Letters Patent. Patented lVIal'. 28, 1922.

Application led January 8, 1921. Serial No. 435,844.

To all 11g/wm t may cof/wem Be it known that. I, KENNETH RUSHTON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Electrie'Locomotives, of which the following is a specifca- Y that in the event of end pressure `on the .trucks the springs will yield and the prestion.

This invention relates to certain improvements in electric llocomotives where the cab extends over two trucks and in which the trucks are connected by along draw bar.

The object of the invention is tov yieldingly connect the pivot pins of the cab to the trucks so that the end'pressure will ynot be taken through the cab but through the trucks and draw bar.

This object -I attain in the following manner, reference being. had to the accompany-f ing drawings, in which: j y

Fig. 1 is a plan view illustrating two trucks ot an electric locomotive connected by a draw bar, and showing the cab in dotted lines; Y j' Fig. 2 is an enlarged sectional plan view on the line 2 2, Fig. 3, showing the yielding connection between a truck and the pivot pin projecting from tlie'cab;

Fig. 3 is a side view of the connections shown in Fig. 2; and Y Fig. 4 is a vertical sectional view on the line 11e-4, Fig. 3. y

1, 1 are two trucks, of any suitable design, tor use in connectionv with an electric locomotive. The inner end of one truck is connected to the inner end of the other truck by a long draw bar 2. The cab 3, shown by dotted lines in Fig. 1, has cross beams 4, Figs. Sand 4, to which are secured the pivot pins 5. These pivot pins extend into bearings 6 mounted on the cross bars 7 of the trucks 1. These bearlngs are shaped, as

shown in. Fig. 2, and have a wing 8 at each- Thebearing is located between end side. plates 9 secured to or yforming part of the cross beams 7 of the trucks. At each end of each plate is a bearing bar 10. These bars are connected together by bolts 11 at the extreme ends and intermediate plates which Y extend through coiled springs 13 and 13* and through a wing 8, as clearly shown in Fig. 4. In the present instance, there are two sets of coiled springs on eachY side of the web, the heavy springs being on the outside and the light spring: being on the inside. i It will be understood that the arrangement of the springs may be varied without departing from the essential featuresof the invention.

Asv shown in Fig. 2, there are springs on each side of each. wing 8 o't' the bearingr` 6 so binding on the pivots of the cab, as the springs at the bearings will yield so that the trucks will readily accommodate themselves to the curve, the cab passing freely around the curve without binding at the pivots.

While I prefer to locate the yielding bearing on each truck, in some instances, one ot the trucks may be provided with a fixed bearingpivoted to receive a pivot pin projecting from the cab, while the other truck will carry a yielding bearing supported by the side springs, as hereinbefore described, sothat anyvariation in the distance between the centers of the pivot pins on the cab and the centers of the bearings on the trucks will be equalized by the movement of the one bearing. Y I prefer. however, to provide a yielding bearing on both trucks.v

It will. also be understood that, in some instances.v the yielding bearings may be carried by the cab and the pivot pins will proj ect from the trucks without departing-from the main features of the invention.

I claim:

l1. The combination of two trucks; a draw bar connecting the trucks; acab extending over both trucks; pivot connections between the c ab and each ofthe trucks; and springs located between each pivot and one of said parts, whereby end. pressure will be taken through the trucks and draw bar.

2. The combination 'in' an electric locomotive, of two trucks; a draw bar connecting` the trucks; a cab mounted above `both trucks; a pivot pin projecting from the cab by the trucks land draw bar and not by the cab. Y

3. The combination of twoV trucks; adraw bar connect-ing- -the trucks; u cab extending over both trucks; two pivot pins projecting from the cab; bearings for the pivot pins, said bearings being carried bythe trucks; and springs located between one of said bearings und its truck so that any end pressure will be taken by the trucks and. draw bi1-r and not by the cab.

4c. The combination in an electric locoinoti've, of` two trucks;` zu drew bar connecting the inner ends of euch truck; ztcenter bearing mounted on each truck, said' center bearing having e wing at each side; an-

enolosure on the` truck for' the center bearing-5 a spring vonV each side oeach Wing and bearlng against the. Walls of the enclosure; Vand A:1- cub extending` over bothbyy the drew bur and not by the cab.

The combination of a trucx having a cross bint at the center; end plates project ing up `from the cross ber; L bearing ber atefichy end ofthe end plates forming en enclosure; e bearing loosely mounted yin the enclosure, said bearing havingewv'ng at euch Side;v coiled springs mounted between v each side of euch wing andhthebers; plates extending through the two bars, efwlng and two springsQ-a-nda cab mountedv above` the trucks and lia-ving a dependingr pivot 1n.
